How to configure energy pulsing on the E5600 with ION Setup.



Goals and Symptoms

Procedure below shows how to configure pulsing on the E5600 meter.

Causes and Fixes

How to configure pulses on E5600:
The PT/CT ratios do not have any effect on the rate of pulses. The screen shown in Figure 1 is available when you setup your meter in ION Setup. It has fewer modules compared to some of the higher end meters. Basic setup is where you can configure the PT/CT ratios.

Figure 1: Basic Setup

The first step is to go in the demand module (refer to Figure 2) and set the Block Length to 15 minutes (this should be the default setting).

Figure 2: Demand Module

After setting the demand interval, select Energy Pulsing and the screen in Figure 3 will appear. The pulses by default are disabled. After enabling the pulses and the selecting the source, the KE Values are then selected.

Ke=energy (kW) per pulse, Minimum value of Ke is 0.001 and Maximum value is 16.

The meter will pulse when Ke > Kwh Del (for the following screen where kWh Del is selected to be the source). In order to check when the meter will pulse the following equation can be used:

Ke (in Kwh units) > Kwh/PT*CT

How to check pulses on the E5600:

Without connecting any device to the meter the following registers can be read through modbus to see if the meter is pulsing through its digital outputs. The registers show ON or OFF status only. If the meter is pulsing the value for the register will be switching between 1 and 0.

KY Output 1 Relay Status
KY Output 2 Relay Status

The other simple test is to connect the digital outputs to the digital inputs of the meter to check the pulses. In which cases the following registers can be read through Modbus to see if the digital inputs are receiving pulsing signals. The registers show ON or OFF status only


External Input 1 Status
External Input 2 Status

Digital outputs can handle at the most 120mA. The Digital Output Specifications in the installation guide gives more detailed specifications.


Once it has been determined that the meter is pulsing properly, master reset the meter. This step is necessary since the meter does not pulse until the first demand interval is completed. For example, if the meter time is at 12:01 pm and the Block length is set to 15 minutes then the first pulse will happen at 12:15pm. This is true even if the meter has accumulated enough energy to pulse. By changing the demand interval to something less than 15 minutes does not help in the meter to pulse early.

Please note: From the Digital output the meter performs KY pulsing, hence after 2 Ke you would see a transition as can be seen in figure 4 below. Make sure on the software side you multiply the pulse counter by a factor of two to get the right number of pulses to determine accurately the energy measured.
